Description

I thought it would be interesting to visually compare the galaxy image you get as Luminosity versus the H-alpha emissions image. The obvious difference is that there is significantly more data in the Luminosity image even though the H-alpha had twice as many subs. If you look more closely at the H-alpha image you can see the prominence of the emission nebula within the galaxy.

These data are being used as part of the HaLRGB image that will come next.
